Here's one...

I'm using Borland Turbo C++ 3.1, and am trying to create a DLL with a class
definition which I can import into my App.  I've decared the class in the DLL
using the EXPORT macro:

   class EXPORT class_name
   {
    ...
   }

and I've included the .lib file for the DLL in my project file. I now need to
put some reference to class_name in my main application code so I can derive
descendant classes from class_name.  How do I do this? Also, in the previous
version I defined class_name in a header file, and included a prototype of
the class at the top of the code ..

  class class_name;

so that I could create pointers to class_name before it was defined.  What is
the appropriate syntax for doing this when class_name is contained in a DLL?

Thanks
